We are getting a 403 “The client application making this request does not have access to this API” only when we post to the endpoint https://dev.twitter.com/ads/reference/post/accounts/%3Aaccount_id/tailored_audiences
It seems like we were getting 200 response earlier, but as of earlier today we are getting 403 consistently.
If we perform a GET request to that url, it works fine.
Any idea what is going on?
